This invention relates to improvements in car construction. 7

One object of the invention is to provide a connecting means for bodyand truck bolsters of railway cars in the form of a combined locking andcenter pin composed of a plurality of sections which may be readilyapplied and removed, and has shouldered engagement with the bolsters,wherein maximum strength is had by providing relatively large completeannular head members at opposite ends of the pin comprising enlargementsat opposite ends of each section.

Another object of the invention is to provide a combined lockingand'center pin for body and truck bolsters of railway cars having alinedcenter pin receiving openings, each provided. with a shoulder at theouter end of its opening, wherein the center pin is composed of aplurality'of sections including a pair of outer members and a combinedfiller and spreading member therebetween, each outer member and thefiller member having heads at opposite ends thereof, and the shouldersof the bolsters are cut away to provide clearance in assembling thesections with the bolsters, and the assembled pin is rotatable to'bringthe head members of the filler in shouldered engagement with thebolsters and the filler member is locked against reverse rotation withrespect to one of said bolsters to prevent disengagement of the headmembers thereof from the corresponding shoulders.

e Other objects of the invention will more clearly appear from thedescription and claims hereinafter following. J

In the drawing, forming a part of this s oecification, Figure 1 is atopplan iew of a portion of the body bolster of a railway car illustratingmy in'iprovemcnts in connection therewith. Figure 2 isa vertical,sectional view corresponding substantially to the line 22 of Figure 1.Figure 3 is a vertical, sectional view substantially in a plane at rightangles to the vertical, sectional View shown in Figure 2. And Figure lis a horizontal, sectional view corresponding substantially to the line4 -4 of Figure 2.

to In saiddrawings, designates a-body bolster and 11 the truck bolsterof a railway can. The truck bolster is .provided withthe usual bearingblopk 12 at the top thereof seated in a pocket 13 on the bolster. Thebody bolster is provided with a depending, cooperating bearingprojection 14, which is of convex spherical formation and cooperateswith the concave top bearing surface on the block 12. The block 12-isalso provided with an annular upstanding flange 15 which enwithin theusual pocket 16 provided at the bottom of the body bolster.

In carrying out my invention, I provide the body and truck bolsters"'ith alined center pin. receiving openings 17 and 18. The bearingbloclr12 is also provided with an opening 19, which registers with theopenings'lt' and 18. The openings of thebody and truck bolsters and thebearing block are preferably of cylindrical cross section and of thesame size. Below the. pin receiving opening 18 of the truck bolster, arelatively large pocket 20 is provided, which, as shown, is ofconsiderably greater width than the pin receiving opening 18, therebyproviding a retaining shoulder 21 at the bottom end of said opening.

he body bolster is also provided with a relatively large pocket 22 abovethe center pin receiving opening 17 thereof, which is of greater widththan said opening, thereby providing an annular retaining shoulder 23surrounding said opening at the uper end therea of. At the upperendof'the pocket 22, the truck bolster walls are recessedatdiametrically opposite sides as indicated at 2525, fora purposehereinafter pointed out. The walls of the openin s 17 and 18.01 the bodyand truck bolsters and the opening 19 of the bearingblocl: 12 arevertically slotted at'diametrically opposite sides, as indicated at Theslots 2 l24l extend through the shoulders 21 and 23: of the truck andbody bolsters, thereby cutting away portions of the shoulders andleaving supporting ledges on diametrically opposite sides of the pinreceiving openings. 7

My impr ved combined locking and center pin co-mprisesbroadly a pair ofouter members AA and a central filler or spreading member B.

The members A are of similar design, each having a shank portionextending through the pin receiving openings and head members 26-26 atthe top and bottom ends of the shah]: portion. The shank of each memberA has a fiat inner face and a curved outer surface which correspondssubstanllyto the curvature of the corresponding wall portions of the pinreceiving openings of the bolsters. The head members 26 are in the formof arcuate flange elements which are of such a size that they will passthrough the pin receiving openings of the bolsters when the end portionsof the flanges are alined with the slots 24 so as to pass through thesome. The head members 26 correspond in to the ledges of the shouldersand preferably eo-extensive therewith. When the two sections A arespread apart, as clearly shown in Figures 3 and 4, the head portionsthereof overhang the retaining shoulders of the body and truck bolsters,thereby preventing separation of the bolstem.

The combined filler and spreader member Bis in the form of a relativelywide flat plate having enlargements 27 and 28 at the top and bottom endsthereof respectively. The enlargements 27 and 28 form head portions adated to cooperate with the reta1nin shoul ers of the body and truckbolsters. enlargements 27 and 28 are of such a size that they passfreely through the slots 24 in assembling the parts, while the fillermember is being inserted within the openings of the bolsters between themembers As will be evident, when the assembled pin is rotated about itsaxis, the head members 27 and 28 at the top and bottom ends of thefiller member B will be brought into shouldered en agement with theretaining shoultiers of the body and truck bolsters.

. Asdnost clearly illustrated in Figure 1, the recesses -25 at the upperend of the pocket 22 of the body bolster are located in a vertical planeat an angle of 90 to an axial plane passing through the slots 24. Whenthe head portions of the filler member are lgoufiit into shoulderedengagement with t ea lsters, the filler plate is disposed in alinementwith the recesses 2525. In order to prevent backward rotation of thefiller with respect to the body bolster, a

ch 29 is employed, which is interldcked iii the body bolster and thefiller ping, As most clearly shown in Figures 2 ma the clip 29 is ofU-shape form and'has the opposite ends thereof seated in the re- 25 andthe side members closely embracing the top end portion of the fillerplate B.

As clearly shown in Figure 2, both the um! members A-A and the fillerplate B are provided with eye members at the top thereof to facilitatehandling of the same and withdrawal of the parts from the center pinreceiving openings of the bolsters. As most clearly shown in Figgure 3,the upper end portion of the plate is laterally enlarged, therebyproviding shouldered engagement with the upper ends of the members A, asindicated at -30. This shouldercd engagement between the plate B and themembers A prevents the plate from dropping between the members A.

In applying my improved combined locking and center pin to the bolstersof a railway car, the sections A-A may be inserted either through thetop of the body bolster or upwardly through the bottom of the truckbolster. The sections A are inserted successively. Assuming that thesection A, shown at the lefthand side of Figure 3, is first applied, thehead portions thereof are so disposed as to register with the slots 24of the bolsters. When in this position, the section A referred to may befreely inserted through the openings of the two bolsters. After havingbeen completely inserted, this section is displaced laterally so as tooverlap the head portions thereof with the shoulders of the body andtruck bolsters respectively. The other section A is then applied in asimilar manner, it being evident that the first section when displacedlaterally entirely clears the slots 24 so as to permit passage of thehead portions of the second section A. When the two sections have beenspread apart, as shown in Figure 3, the filler plate B is appliedtherebetween by inserting the same through the top of the body bolster.lVhen the filler plate has been completel inserted, the head members atthe top and bottom ends thereof are disposed respectively above andbelow the retaining shoulders of the body and truck bolsters. With theparts thus assembled, the pin is rotated about its vertical axis throughan angle of 90, thereby bringing the filler plate into alinement withthe recesses 25-25 of the pocket 22 of the body bolster. As will beevident, when the parts are thus positioned, the filler plate hasshoulderedengagement with both the body and truck bolsters. The lockingclip 29 is then applied by engaging the same over the upstanding eyeportion of the filler plate and seating the ends thereof in the recess25. As hereinbefore pointed out, the clip thus locks the assembled pinagainst rotation with respect to the body bolster. When it is desired toseparate the bolsters or remove the combined locking and center pin, theclip 29 is first disengaged from the filler member and the recesses25-25. The entire pin is then rotated about its axis until the headportions of the filler member are alined with the slots 24 of thebolsters. As will be evident. the filler member may then be freelywithdrawn upwardly throughthe body bolster, the head portion 28 at thebottom end thereof passing freely through the slots. After the fillermember has been removed, either of the sections A may be displacedlaterally inwardly until. the opposite end portions of'the flanges,which form the top and bottom heads, are in alinement with the slots,whereupon the section may be withdrawn either through the body or truckbolster, the heads passing through the slotted portions of the bolsters.The other section A may then be displaced laterally and removed in asimilar manner. a

From the preceding description taken in connection with the drawings, itwill be evilent that I have provided an exceedingly rugged center pin ofthe sectional type wherein completeannular head members are provided atopposite ends to assure shouldered engagement with the retainingshoulders of the bolsters at all times and thereby providing maximumtensile strength in all relative angular positions of the body and truckbolsters.

A decided advantage is also obtained by locking he assembled pin againstrotation with respect to one of the bolsters in that all danger of thepin shifting to a position where the head memoers of the filler memberwill become disengaged is avoided.

I have herein shown and described what I now consider the preferredmanner of carrying out my invention, but the same is merely illustrativeand I contemplate all changes and modifications that come within thescope of the claims appended hereto.
